Devs are adding netplay (click to see netplay testing) to the Atomiswave/Naomi/Dreamcast emulator 'Demul'. When Demul 0.5.6 comes out we should hopefully be able to play Atomiswave games online! You can actually play a few online already with Mame32++ but they run very slowly so there's no point. Demul runs the games at full speed.

It means that soon we can probably play Hokuto no Ken, Rumble Fish, KOF Neowave on kaillera - and in future Samurai Shodown 6, Neogeo Battle Coliseum, KOF XI, Rumble Fish 2 and Metal Slug 6 (the latter 4 are still not dumped yet)

For Naomi pad settings, go to the Jamma settings. I notice that the fifth button for GG (Dust) and MB (multipurpose macro) is assigned to push 5 even though in arcades it's in the 6th hole. So for button mappings in CvS2 assign (left to right, top to bottom):

I found out myself you have install direct x 9 from the direct x website even if you have direct x 11 like I did. Run the installer then the plugins will work. Best one for me is gpudxv3.

Just have to adjust to it a bit is all. We played about 7-8 games and no desync happened. Though when we first tried to play online it crashed for some reason. Second try it worked though. Not sure why that happened but as long as it works it's fine.

Situation for SS6 and other SNK games rom dumping progress:http://www.emu-land.net/forum/index.php ... .2575.html-Part of Atomiswave game carts (including SS6, KOFXI, NGBC, Metal Slug 6 etc) use different type of chip-To dump roms from such carts, a special equipment is needed (and rom dumpers currently lack it)-In particular, they would need to construct a custom adapter, which means buying an programmator adapter for this type of chip (around 300$) + big amount of soldering work-Guru has carts for SS6, KOFXI, NGBC but he is unable to dump them because he too lacks the equipment, and most likely will continue to lack it until someone donates $$-Of course even if one donates, no one will guarantee that those games will be emulated correctly once dumped, because no one tried to emulate them before.

more stuff about Demul from SRK thread

According tohttp://guru.mameworld.info/atomiswave/index.htmlGames like NGBC, SS6, KOF XI were dumped already (and NGBC and KOFXI were already added to latest MAME release 140u3). For those who want to test them, google rom name together with the "mamev" word

Now to find out if they work on Demul...

EDIT: I tried NGBC on MAME and it gave me incorrect CHD warning, and afterwards the only thing shown by game was the "ALL BACKUP DATA CLEARED" notice

Update:Information on Guru's site isnt entirely correct.NGBC was dumped by Guru, while KOFXI was dumped by CaH4e3 (russian), and SS6 actually isnt dumped yet (but will be, since now both have the equipment which allows to dump roms of this type)

NGBC and KOFXI will not work in MAME, because it does not support the emulation of this type of Atomiswave roms.However they do work in curren W.I.P. version of Demul, and once it gets public release, everyone will be able to play NGBC and KOFXI online using Demul.

Im gonna say that currently KOFXI and NGBC run slower than usual, although I hope their emulation can be optimized. Against GGAC's 60 fps, KOFXI would jump between roughly 30~50 fps and NGBC between 20~40 fps. Its because those games utilize 3d-based backdrops or something, that results in big quantity of small textures being displayed at same time each frame, which slows the emulation. There are almost none graphic glitches it seems (minor ones in select screen/continue screen HUDs). Right now these games look better with sound off, because of sound lags. Since SS6 is relatively the same in construction (lowres 2D sprites, highres backdrops which utilize 3D), Im expecting it to run relatively the same as mentioned 2 games.
